...“The motions of every individual, no matter what his work may be, have been studied and standardised....

Assembly of braiding machines ... “where eighteen braiders had been assembled by one man in a day, it now becomes possible to assemble 66 braiders per man per day, with no increase in fatigue” (97)....

The latest method 1) micro-motion studies ... 2) use of the “chronocyclograph” (97)....

I. The “micro-motion clock” is placed in front of the worker and it registers “different times of day in each picture of a motion picture film” (98)....

II. “The chronocyclograph method of making motion study consists of fastening tiny electric light bulbs to the fingers of the operator, or to any part of the operator or of the material whose motion path it is desired to study”... (the movement of the light, its track, is photographed) (98).

This must be taught in the schools.

At present an “enormous waste” (102) is occurring from scattered, duplicated, etc., “investigations”.... “It is the work of the United States Government to establish such a bureau of standardisation of mechanical trades. The standards there derived and collected would be public property, and original investigators could invent from these standards upwards” (103)....
